fix: enforce take_profit_pct in HOLD evaluation loop (#163)

HOLD 판정 후 보유 포지션에 대해 stop_loss와 함께 take_profit도 체크하도록 수정.
AI가 생성한 take_profit_pct가 실제 거래 로직에 반영되지 않던 구조적 결함 수정.

- HOLD 블록에서 loss_pct >= take_profit_threshold 조건 추가
- stop_loss와 상호 배타적으로 동작 (stop_loss 우선 체크)
- take_profit 기본값 3.0% (playbook 없는 경우 적용)
- 테스트 2개 추가:
  - test_hold_overridden_to_sell_when_take_profit_triggered
  - test_hold_not_overridden_when_between_stop_loss_and_take_profit
